DNA Replication and Transcription Review

What happens in interphase?

• Mitosis

• The cell is growing and replicates its DNA

• The cell is in its resting phase

• None of the above

Why does DNA matter?

• DNA codes for traits in an organism

• DNA is essential for all living organisms

• More function cells cannot be made without putting DNA into those new cells

• DNA is replicated for the development of new cells

• All of the above.
